Running right at max power jetting tends to be harder on parts and takes more attention to plug chops and such.
For normal riding, just keep going till you're happy and if you're not sure how far lean you are, back off a size. Check the plug for a few days to be sure, then ride it!
Ok, new to this.
Iím going off feel at this point. My engine is not smoking, running smoother, #3rd notch on the needle. Iíve not pulled the plug yet to look at color (tan is the zone?). Is that the true measure of safe range? It does pull me alongÖwish I could change gears!
